Method and computer-readable media for creating verified business transaction documents

ABSTRACT

A method, and computer-readable media for performing the method, for creating verified business transaction documents. Electronic transaction documents are received from authenticated users, version identifiers are assigned to these documents, and the documents and version identifiers are stored in a database. Authenticated users may select a single version for “finalization” and a non-alterable document with a verification code is created and stored in the database for retrieval by users.

RELATED APPLICATIONS

This nonprovisional patent application claims priority benefit, with regard to all common subject matter, of earlier-filed U.S. provisional patent application titled “Document Exchange Version Identifier”, Ser. No. 60/928,905, filed May 11, 2007. The identified earlier-filed application is hereby incorporated by reference in its entirety into the present application.

BACKGROUND OF THE INVENTION

Various on-line collaboration systems are used to facilitate the exchange of business transaction documents via secure Internet websites. These systems are particularly useful in situations in which multiple versions of a document are exchanged among multiple users. Ideally the versions of different documents are presented in an organized manner allowing retrieval of both current and prior versions of each of the documents involved.

In many cases these documents are exchanged in an environment involving multiple “adverse” parties on different sides of a transaction. For example, document drafts may be exchanged between a buyer and seller of a business (and their attorneys and advisers). In the situations it is desirable that the document repository be a neutral service not associated with either of the transaction parties.

But despite the efficient use of Internet-based document exchange systems, the final step in most significant transactions is still the physical signing of the documents. In the case of significant transactions, dozens of documents, many of which may be 50 or more pages in length, must be signed at the “closing.” In some cases there is not a single closing and instead each party prints the “final” document and signature pages are exchanged. While an on-line document exchange system allows the parties to more efficiently reach the point of agreement upon a “final” version that will be signed by the parties, there remains some uncertainty as to whether the printed document being signed at the closing (or separately printed and signed by each of the parties) is the “final” document expected by the parties. Unfortunately, the only way to accurately verify the appropriateness of the printed document presented for signature is to physically compare that document with a printed version of the intended “final” version. This process is time-consuming and prone to error, particularly in complex transactions with multiple lengthy documents.

SUMMARY OF THE INVENTION

The present invention addresses these issues with an on-line system of exchanging transaction documents by providing a new method of creating a verified transaction document. In this invention, a document exchange system functions as a neutral repository of all document drafts exchanged by the parties. If in a transaction twenty versions of a particular agreement were exchanged, each of these twenty versions is available for retrieval. Related information such as the sequence of receipt of document versions and the identity of the person providing each document version are also presented. As a final step, this invention allows the parties to designate a single version (typically the most recent version) of the document as the “final” version. The “final” document is converted to a non-alterable format (such as Adobe Acrobat PDF) and a verification code is added to the document. For example, the verification code may be added as a “footer” to the “final” version. This verification code may constitute symbols, text, or other identifying information and it may be located anywhere on or in the document. This modified, non-alterable document is automatically added to the versions available in the document exchange system database. Optionally, the document exchange system may preclude the submission of future drafts after such a “final” document has been generated.

The parties preparing to complete a transaction may open and print the final version with the verification code and text included. The parties signing the documents can look for the verification code and confirm that an incorrect version was not inadvertently printed. Ideally the verification code would appear on each page of the printed final document. While there is some remaining risk of fraudulent document alteration, the verification code and accompanying text (which could include graphical elements) could be sufficiently difficult to accurately copy it would require a substantial amount of dishonest effort. In such a case other remedies would be available against a dishonest party.

DETAILED DESCRIPTION OF THE INVENTION

This invention is comprised of the method described in more detail below. The invention also comprises one or more computer-readable media having computer-executable instructions embodied thereon and associated processors and memory for performing this method. Computer-readable media include both volatile and nonvolatile media, removable and nonremovable media, and contemplates media readable by a database, a switch, and various other network devices. By way of example, and not limitation, computer-readable media comprise media implemented in any method or technology for storing information. Examples of stored information include computer-useable instructions, data structures, program modules, and other data representations. Media examples include, but are not limited to information-delivery media, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile discs (DVD), holographic media or other optical disc storage, magnetic cassettes, magnetic tape, magnetic disk storage, and other magnetic storage devices. These technologies can store data momentarily, temporarily, or permanently.

FIG. 1 shows in general the collection of multiple business transaction document versions in a version archive for exchanging business transaction documents. To facilitate the negotiation process, the document versions exchanged would typically be in a format that can be easily modified, such as a Microsoft Word format. When a “final” version is identified, a verification code is generated and added to the identified “final” document. Ideally at this point the document is converted to a “non-alterable” format (like Adobe Acrobat PDF). This non-alterable version is added to the database for access by users, who can then print and sign the document.

FIG. 2 identifies more specifically steps of the method (and computer-readable media) that constitute this invention. In a preferred embodiment of the invention application software (created, for example, using ColdFusion 8) is installed on a computer with an operating system software (such as, for example, Windows 2003 server). The process begins with a user providing an authentication request. The application software authenticates users seeking access to the system (for example, via the Internet) by comparing a user provided user name and password against a list of authorized list of user names and passwords. Preferably a “firewall” is also present between authenticated users and the application server to allow passage of only certain types of data packet transmissions (such as, for example, http or https).

The application software receives electronic document versions submitted by authenticated users and assigns version identifiers associated with those document versions. The application software communicates with a database server and associated software (such as, for example, Microsoft SQL Server) for storage of these electronic document versions and related version identifiers. The application software and database server software may be installed on one computer or on different computers. For purposes of this application, “database” includes the computer-readable media and associated processors necessary to index and store electronic document files on one or more computers. As shown in FIG. 2, electronic documents received by the application software are stored in the database, together with the associated document version identifiers. Authenticated users may retrieve electronic document versions from the database.

In the most important step of the present invention, authenticated users may select a specific document version for “finalization.” The application software modifies the selected file using a “.NET” object to convert the document to a non-alterable format and adds a verification code to that document. The finalization step may be commenced by any authenticated user, or alternatively only by certain authenticated users. Where the document exchange system provides greater control rights to specific users (often called “administrators”) the present invention could provide that only these administrators, or alternatively an administrator from each party to the transaction, have the ability to “finalize” a document. As described above, the “finalization” step, represented by the “Modify Document” step in FIG. 2, involves the creation of a non-alterable document with a verification code added. The verification code may be added prior to the creation of the non-alterable document or after creation of the non-alterable document. “Non-alterable document” means a document that, once opened by a user can not be modified by that user or another authenticated user.

After a user has identified a document version for finalization, a warning screen should be presented confirming that the user wishes to “finalize” the document. The system would ideally permit the finalization of only one version, but as an alternative if a second version is later “finalized” the previously finalized version could be again modified to include text (like “Superseded”) to reflect that a different version had been subsequently finalized. In this case the second finalized version could include a modified verification code with text like “Revised Final Document.”

Ideally the finalization of one version would “lock” the database and prevent further posting of additional versions of that document. Alternatively, selected users could be given the authority to unlock the database after finalization to permit the posting of additional versions.

Preferably the verification code comprises the logo of the independent provider of the document exchange system, the words “Final Document,” the date of finalization, and a global unique identifier (GUID). The total size of the verification code should be approximately one half (½) inch high and one and one-half to two (1½ to 2) inches long. The verification code visibly appears in the document, whether the document is viewed on a display screen or printed.

The modified document, with verification code and in a non-alterable format, is added to the database and is available for retrieval by authenticated users as another version of the document.

Referring to FIG. 3, an exemplary operating environment suitable for implementing embodiments of the present invention is shown and designated generally as computing device 100. Computing device 100 is but one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality of the invention. Neither should the computing environment 100 be interpreted as having any dependency or requirement relating to any one or combination of modules/components illustrated.

Embodiments may be described in the general context of computer code or machine-useable instructions, including computer-executable instructions such as program modules, being executed by a computer or other machine, such as a personal data assistant or other handheld device. Generally, program modules including routines, programs, objects, modules, data structures, and the like, refer to code that performs particular tasks or implements particular abstract data types. Embodiments may be practiced in a variety of system configurations, including hand-held devices, consumer electronics, general-purpose computers, specialty computing devices, etc. Embodiments may also be practiced in distributed computing environments where tasks are performed by remote-processing devices that are linked through a communications network.
